BERTHOLD FLICK AND PAUL REINIG, OF BERLIN-MARIENDORF, GERMANY.

FLYING DEVICE.

To all whom it may concern:

Be it known that we, BERTI-IOLD FLTCK and PAUL REINIG, subjects of the Grand Duke of Baden, residing at Berlin-il'larzendorf, Germany, have invented certain new and useful Improvements in Flying Devices; and we do hereby declare the following to be a full. clear, and exact descrlption of the invention, such as will enable others skilled in the art to which. it appertains to make and use the same.

This invention relates to a flying apparatus based onthe principle of oblique surfaces in combination with av suitable propel;

ling device, in which the hearing: surfi'tt have a new arrangement insuring a smaller air resistance, increased stability and possi: bility of almost'nnlimitcd increase l'rt size for the purpose of heavy transport.

A construction according to this ingention is illustrated in the accompanythg drawing in which Figure l is a side elevation of the apparatus, Fig. 2 a plan, Fig. -3 a front elevation, Fig. 4 a vertical cross-section through the flying apparatus on line All of Fig.1, and Fig. a cross-section on line C-D of Fig. 1. v

llnlike in the well known gliding; flying apparatus. the bearing surfaces'in the construction actor-ding to this invention have considerably greater length than width, the direction of length being understood to be that of the flight. These surfaceshave in places slight lateral extensions used for steadyingthe whole system, that is tosay, for preventing oscillations or even tilting over. i

The bearing surfaces are double and ar ranged one above another, that is to say, the apparatus is a socalled biplane. It consists of two superposed frames an upper frame 1 and a bottom frame 2 connected together by vertical struts 3 and provided with transverse ribs l which, by their curvature, give the bearing surfaces the desired shape. The frames are covered with suit able material and this covering, that is to say, surfaces are indicated in the drawing by hatching.

The upper bearing surface forms an inverted flat trough, the deepest point of which is situated at about one-third of the I length of the front portion. The front and back cross-frame parts 5 and 6 are straight. The bottom bearing surface is formed of two parts, a front part 31 and a rear part 32 separated from each other by a free space. While the front part 81 of the bottom bearing surface is arched only in the transverse direction, the rear part 32 is curved in the same way as the upper bearing surface, that is to say, forms a trough upward.

On the front part of the bottom bearing surface 82 is mounted the pilot seat 33 which, for the purpose of reducing the air pan be closed outward by rounded oil walls.

In the intermediate space between the front and rear parts of thc'bottom bearing surface, is arranged the engine 34: with the two propellers 15 and 16, one of which is 'in front, and the other at the back of the engine, and of which each can rotate in opposite direction to the other. This arrangement obviates any turning momentum which would be liable to produce a tilting of the Whole system.

The upper surface or air-plane has lateral i wings or extensions 17 and 18 at its extreme front and rear portions respectively. These wings are curved upwardly, ject from the side edges of the 'frame 1. Narrow upwardly curved extensions 35 also project laterally from the side edges of the frame 1, and extend longitudinally between the curved. wings l7 and 18. These wings 17 and 18 and the extensions operate to steady the machine by contact with the air which escapes laterally from under the upper air-plane. The lower frame 2 is also provided with wings 25 for steadying the machine. side the frame 2 at the sidesof the motor 35, and in front of the pilot seat 33. The front ends of the wings 25 are pivoted at 26 to the frame 2, and the wings 25 can be arranged in line with the frame 2 and the lower airplane, or they can be set at any desired acute angle to the frame, and they are shown inand they pro-' These wings'25 are arranged-outclined with their rear ends above the frame.2.,

The wings izfiinayjie adjusted and secured-- by hand in any approved manner. T he frames 1 and 2 have auxiliary frames 36 and 37 at their rear ends which are inclined toward each other at an acute angle and which have their rear ends secured toyether.

A riild lel' 23 is mounted on a horizontal pivot at the rcar ends of the frames 36 37. ltudders 20 are mounted onvertical spindles 15) atv the middle parts of the frames 36 37, and are arranged one on each side of the machine. The means for operating these rudders and the rudder 23 are not shown as they are of any approved kind.'

The upper bearing surface can be preferably made a. little longer than the bottom one, so that in the horizontal position of the frames, the front .end of the upper frame slightly ,projectsbeyond the front end of the bottom frame.

The whole apparatus is provided, for resting on the ground and. starting, with wheels 27 and 28, and the axle supports are calculated in such manner that for the purpose of starting, the front end occupies a higher position than the rear end, so that during the forward movement on the ground, the air current strikes the bearing surfaces from below.

For further sleadying, and also for guidint, the airdmdcr the gliding surfaces, both the bottom and the upper gliding surfaces are provi led with downward flanges 39 40. 'lhe gliding suriacescan also be provided at their bottom su face with other downward ribs or longitudinal projections 41 as shown by way of example in the case of the upper bearing surface in Figs. 3-5.

For the purpose of landing, the apparatus provided with gliding runners 29 which can be asrangcd at any point, for in stance close to the front Wheels or under the engine, so that when the wheels mounted in a very elastic manner, are forced back in landing, the'weight of the vehicle rests on the runners and utilized for braking.

In order to insure an increased speed of flight after the desired height has been reached, the propeller spindle is arranged so that it can be turned, in such manner that the whole engine with the propellers can be'turncd about a horizontal axis for instance at 30. This is el'lccted "from the pilot seat. 23 by means of a suitable device. Tll'ieinotor or engine 34: has its casing pivotcd ,at '30 to one of the uprights 3, and its level du be adjusted in any approved way,- and whim adjusted it may be secured by any suitable fastenirg. The propeller shutt can be thereby placed C(mipletely or practically in the longitudinal directi n of flight, while normally it forms a certain angle with the said longitudinal direction. l'n that way,

direction of the bearing surfaces. The lat- ,tcr do not therefore form any obstacle for the advance, and the speed can be very considerably increased in that manner.

This arrangement, in addition to the already mentioned increase of stability, increase of speed and possibility of safe landing, has the advantage of enabling the a aratus to be made of very considerabe size without any difficulties. While in liding flying apparatus with hearing sur aces extended in the transverse direction there is very soon reached a limit of size owing to the impossibility of increasin the strength of the whole system to the esired extent, the strength in the construction according to this invention can never form an obstacle to the increase of size of the apparatus, as the propelling power acts in t a longitudinal, that is to say, in the most favorable, direction. Another advantage is finally the ease of transporting the whole on the ground, and moreover owing to the small width, the possibility of starting from the roads.
